The touch sensor 130 is an example of a contact detection unit and detects contact of the finger with the top surface of the operation dial 110. In a case where the contact is detected, the touch sensor 130 outputs an ON signal. The touch sensor 130 has a circular contact detection region, and substantially the entire region on the upper-end surface of the inner peripheral part 112 is set as the contact detection region.

As described above, the operation by the operation dial 110 becomes valid only in the case where the outer peripheral part 114 is rotationally operated while the upper-end surface (top surface) of the inner peripheral part 112 which is the top surface is touched. That is, the lock is set in a state where the top surface is not touched, and the lock is released by touching the top surface. A character of “UNLOCK” indicating that the lock is released in a case of touching the top surface is displayed on the upper-end surface of the inner peripheral part 112 which is the top surface. The character is displayed on the upper-end surface of the inner peripheral part 112 in a printed or engraved manner.

The outer peripheral part 114 has a cylindrical shaft portion 114A on the coaxially lower portion, and the shaft portion 114A is rotatably supported by the operation dial support frame 116 through bearings 118.

The outer peripheral part 114 is supported so as to be rotatable in normal and reverse directions. In FIGS. 3 and 5, an arrow direction (counterclockwise rotation direction) indicated by a reference numeral R+ is referred to as a plus rotation direction, and an arrow direction (clockwise rotation direction) indicated by a reference numeral R− is referred to as a minus rotation direction.

A click mechanism 120 is provided in the operation dial support frame 116. The click mechanism 120 generates a click feeling in the rotation of the outer peripheral part 114 of the operation dial 110.

The click mechanism 120 comprises a click groove-metal plate 120A, click balls 120B, and click springs 120C.

The click groove-metal plate 120A has the disc shape that comprises a circular hole at the center thereof. The click groove-metal plate 120A is fixed to the shaft portion 114A of the outer peripheral part 114 by passing the shaft portion 114A of the outer peripheral part 114 through the center hole thereof. The click groove-metal plate 120A is disposed coaxially with the outer peripheral part 114 and rotates together with the outer peripheral part 114.

The click groove-metal plate 120A is provided with a plurality of click grooves 120 a that are formed on the same circumference at regular intervals. The click grooves 120 a are provided on the upper surface of the click groove-metal plate 120A as spherical depressions. The disposition interval of the click grooves 120 a is an interval that generates the click feeling.

The click balls 120B are members that are fitted to the click grooves 120 a and generate the click feelings. The click balls 120B are provided in the operation dial support frame 116. The operation dial support frame 116 comprises click ball-receiving holes 116A that receive the click balls 120B. The click ball-receiving holes 116A are provided parallel to the rotation axis of the outer peripheral part 114 as bottom holes. Further, the click ball-receiving holes 116A are provided at positions facing the click grooves 120 a.

The click springs 120C are members that bias the click balls 120B to the click groove-metal plate 120A. The click springs 120C are received in the click ball-receiving holes 116A.

The action of the click mechanism 120 having the above-mentioned configuration is as follows.

In a case where the outer peripheral part 114 of the operation dial 110 is rotated, the click groove-metal plate 120A is rotated. In a case where the click groove-metal plate 120A is rotated, the click balls 120B are fitted to the click grooves 120 a at regular angular intervals. Accordingly, the click feelings are generated at regular angular intervals.

Further, in a case where the rotation of the click groove-metal plate 120A is stopped at the time of generation of the click feeling, the click balls 120B are fitted to the click grooves 120 a. Accordingly, the rotation of the click groove-metal plate 120A is stopped. That is, as long as the click groove-metal plate 120A is not rotated with a load equal to or larger than a certain level, a stop state of the click groove-metal plate 120A is maintained. The state where the click balls 120B are fitted to the click grooves 120 a and the rotation of the click groove-metal plate 120A is stopped is referred to as click-stop.

In a case where a click-stop position is referred to as a click position, the number of click positions is the same as the number of click grooves 120 a. The intervals of the click positions are also the same as the intervals of the click grooves 120 a. For example, in a case where the number of click positions per rotation is 10, the disposition interval of the click grooves 120 a becomes 36°. In this case, in a case where the outer peripheral part 114 is rotationally operated, the click feeling is generated at 36° interval. Further, it is possible to perform the click-stop at 36° interval.

The rotation of the outer peripheral part 114 of the operation dial 110 is detected by a rotation detection unit 126. The rotation detection unit 126 detects the rotation direction and a rotation amount of the outer peripheral part 114 of the operation dial 110. The rotation detection unit 126 is formed of a rotary encoder and detects the rotation of the outer peripheral part 114 of the operation dial 110 to detect the rotation direction and the rotation amount of the operation dial 110.

For example, in the case where the number of click positions per rotation is 10, it is possible to detect that the operation dial 110 is rotationally operated by one click in the plus direction R+ by detecting rotation by 36° in the plus direction R+.

[Setting System by Using Operation Dial and Sub-Display]

«Configuration»

FIG. 7 is a block diagram showing the schematic configuration of a setting system using the operation dial and a sub-display.

As described above, the operation dial 110 is valid only in the case where the operation thereof is performed while the top surface is touched. Further, the sub-display 16 displays the setting value of the item to be set by the operation dial 110.

As shown in FIG. 7, a setting system 150 using the operation dial 110 and the sub-display 16 comprises a switching unit 152 that switches between validity and invalidity of the change in the setting value by the operation dial 110 according to a detection result of the touch sensor 130 provided in the operation dial 110, a setting value change unit 154 that changes the setting value in response to the operation of the operation dial 110 in the case where the change in the setting value is valid, a sub-display display control unit 72A that controls the display on the sub-display 16, a setting item selection unit 156 that selects the item to be set by the operation dial 110, and a setting item setting unit 158 that sets the item to be set by the operation dial 110 according to a selection result by the setting item selection unit 156.

The switching unit 152 switches between validity and invalidity of the change in the setting value by the operation dial 110 according to the detection result of the touch sensor 130. As described above, in the digital camera 1 of the embodiment, the operation of the operation dial 110 becomes valid only in the case where the operation dial 110 is operated while the top surface is touched. Accordingly, the switching unit 152 validates the change in the setting value by the operation dial 110 only while the contact is detected by the touch sensor 130.

A function of the switching unit 152 is provided as one function of the system controller 80. That is, a microcomputer executes the predetermined control program and thus the system controller 80 functions as the switching unit 152.

In the case where the change in the setting value is valid, the setting value change unit 154 changes the setting value in response to the operation of the operation dial 110. The setting value change unit 154 changes the setting value of the item to be set by the operation dial 110 according to a detection result of the rotation detection unit 126. That is, the setting value of the item to be set by the operation dial 110 is changed according to the rotation amount and the rotation direction of the operation dial 110.

A function of the setting value change unit 154 is provided as one function of the system controller 80. That is, a microcomputer executes the predetermined control program and thus the system controller 80 functions as the setting value change unit 154.

The sub-display display control unit 72A is one example of a display control unit. The sub-display display control unit 72A controls the drive of the sub-display drive unit 72 to control the display on the sub-display 16. As described above, the sub-display 16 displays mainly the setting contents of the digital camera 1. The information displayed on the sub-display 16 includes at least the information on the setting value of the item to be set by the operation dial 110. The sub-display display control unit 72A acquires information necessary for the display on the sub-display 16 to control the display on the sub-display 16.

A function of the sub-display display control unit 72A is provided as one function of the system controller 80. That is, a microcomputer executes the predetermined control program and thus the system controller 80 functions as the sub-display display control unit 72A.

FIG. 8 is a plan view showing a display example of the sub-display.

As shown in FIG. 8, the sub-display 16 displays shutter speed information i1, F-number information i2, international organization for standardization sensitivity (ISO) information i3, exposure correction value information i4, and imaging mode information i5 as the setting contents of the digital camera 1. These pieces of information are pieces of information on the items that can be set by the operation dial 110. That is, in the digital camera 1 of the embodiment, the shutter speed, the F-number, the ISO sensitivity, the exposure correction value, and the imaging mode can be set by the operation dial 110, and the sub-display 16 displays the setting values of the items that can be set by the operation dial 110.

Further, the sub-display 16 displays a lock mark m1 indicating that the operation dial 110 is locked, that is, the change in the setting value by the operation dial 110 is invalid. The lock mark m1 is formed of a figure including a character of “LOCK”. In the case where the operation dial 110 is locked, the lock mark m1 is displayed.

Furthermore, the sub-display 16 displays a selection mark m2 indicating the item that can be set by the operation dial 110. The selection mark m2 is formed of a triangular figure and is displayed at a position indicating a position of an item that can be set by the operation dial 110. FIG. 8 shows an example in a case where the shutter speed is set by the operation dial 110. In this case, the selection mark m2 is displayed at a position indicating a position where the shutter speed is displayed.

The setting item selection unit 156 selects the item to be set by the operation dial 110. In the digital camera 1 of the embodiment, the item to be set by the operation dial 110 is set on the setting screen. In a case where the setting screen is called from the menu screen, an item of “operation dial setting” appears as one of the items that can be set on the setting screen. In a case where the item of “operation dial setting” is selected, a selection screen of the items to be set by the operation dial 110 appears on the main-display 14, and the selection of the items to be set by the operation dial 110 is possible. The selection is performed by using the selector buttons 39, the menu button 38, and the BACK button 40. That is, in the digital camera 1 of the embodiment, the main-display 14, the system controller 80, the selector buttons 39, the menu button 38, the BACK button 40, and the like cooperate to form the setting item selection unit 156.

The setting item setting unit 158 sets the item to be set by the operation dial 110 according to a selection result by the setting item selection unit 156. The setting item setting unit 158 is formed of the system controller 80. That is, the system controller 80 executes the predetermined control program to function as the setting item setting unit 158.

In a case where the shutter speed is selected as the item to be set by the operation dial 110, the setting value change unit 154 changes the shutter speed in a predetermined order in response to the operation of the operation dial 110. That is, in a case where the operation dial 110 is rotationally operated in the plus direction, the shutter speed is advanced for each one click. In a case where the operation dial 110 is rotationally operated in the minus direction, the shutter speed is lowered for each one click.

In a case where the F-number is selected as the item to be set by the operation dial 110, the setting value change unit 154 changes the F-number in a predetermined order in response to the operation of the operation dial 110. That is, in a case where the operation dial 110 is rotationally operated in the plus direction, the F-number is advanced for each one click. In a case where the operation dial 110 is rotationally operated in the minus direction, the F-number is lowered for each one click.

Furthermore, in a case where the ISO sensitivity is selected as the item to be set by the operation dial 110, the setting value change unit 154 changes the ISO sensitivity in a predetermined order in response to the operation of the operation dial 110. That is, in a case where the operation dial 110 is rotationally operated in the plus direction, the ISO sensitivity is advanced for each one click. In a case where the operation dial 110 is rotationally operated in the minus direction, the ISO sensitivity is lowered for each one click.

Further, in a case where the exposure correction value is selected as the item to be set by the operation dial 110, the setting value change unit 154 changes the exposure correction value in a predetermined step width in response to the operation of the operation dial 110. That is, in a case where the operation dial 110 is rotationally operated in the plus direction, the exposure correction value is advanced in the predetermined step width to the plus side for each one click. In a case where the operation dial 110 is rotationally operated in the minus direction, the exposure correction value is lowered in the predetermined step width to the minus side for each one click.

Further, in a case where the imaging mode is selected as the item to be set by the operation dial 110, the setting value change unit 154 changes the imaging mode in a predetermined order in response to the operation of the operation dial 110. In the digital camera 1 of the embodiment, program, shutter speed priority, aperture stop priority, and manual are prepared as the selectable imaging modes.

Here, the program refers to a mode in which an imaging person can change a combination of the F-number and the shutter speed while the exposure is constantly maintained. The mode is an imaging mode in which so-called program shift is possible. In a case where “program” is selected as the imaging mode, a character of “P” is displayed on the sub-display 16.

The shutter speed priority refers to a mode in which the camera automatically decides an F-number such that the proper exposure is achieved for a shutter speed selected by the user. In a case where “shutter speed priority” is selected as the imaging mode, a character of “S” is displayed on the sub-display 16.

The aperture stop priority refers to a mode in which the camera automatically decides a shutter speed such that the proper exposure is achieved for an F-number selected by the user. In a case where “aperture stop priority” is selected as the imaging mode, a character of “A” is displayed on the sub-display 16.

The manual refers to a mode in which the user selects the shutter speed and the F-number. In a case where “manual” is selected as the imaging mode, a character of “M” is displayed on the sub-display 16.

«Action»

Hereinafter, a setting method by using the operation dial and the sub-display will be described.

FIG. 9 is a flowchart showing a procedure of the setting change by using the operation dial.

First, it is determined whether the operation dial 110 is operated (step S11). Whether the operation dial 110 is operated is determined based on an output from the rotation detection unit 126. That is, in a case where the rotation detection unit 126 detects the rotation of the outer peripheral part 114 of the operation dial 110, the operation dial 110 is determined to be operated.

In the case where the operation dial 110 is determined to be operated, then it is determined whether the touch sensor 130 is turned ON (step S12). That is, it is determined whether the top surface of the operation dial 110 is touched by the finger.

In a case where the touch sensor 130 is turned ON, the setting value of the item to be set by the operation dial 110 is changed in response to the operation of the operation dial 110 (step S13). For example, in the case where the item to be set by the operation dial 110 is the shutter speed, the shutter speed is changed in response to the operation of the operation dial 110.

On the other hand, in a case where the touch sensor 130 is turned OFF, that is, in a case where the operation dial 110 is not operated in a state where the top surface of the operation dial 110 is not touched by the finger, the change in the setting value cannot be performed. In this case, the display of the lock mark m1 on the sub-display 16 is turned on and off (step S14).

In this manner, in the digital camera 1 of the embodiment, the change in the setting value by the operation dial 110 is possible only in a case where the operation dial 110 is rotationally operated while the top surface is touched. That is, the lock of the operation dial 110 is released only in the case where the operation dial 110 is rotationally operated while the top surface is touched, and the operation dial 110 is locked in other cases.

FIG. 10 is a plan view of the digital camera showing an operation method of the operation dial in a case where the change in the setting value is valid.

As shown in FIG. 10, the operation dial 110 is rotationally operated while the top surface is touched to validate the operation of the operation dial 110.

FIG. 11 is a plan view of the digital camera showing the operation method of the operation dial in a case where the change in the setting value is invalid.

As shown in FIG. 11, in a case where the operation dial 110 is rotationally operated while the top surface is not touched, the operation of the operation dial 110 becomes invalid.

In the case where the operation of the operation dial 110 is invalid, that is, in the case where the operation dial 110 is locked, the lock mark m1 is displayed on the sub-display 16. In the case where the operation of the operation dial 110 is invalid, that is, in the case where the operation dial 110 is rotationally operated in the state where the operation dial 110 is locked, the lock mark m 1 is turned on and off. Accordingly, it is possible to be more easily recognized that the operation dial 110 is locked.

The system controller 80 executes a predetermined setting program to implement the setting processing.

According to the digital camera 1 of the embodiment as described above, in the case of operating the operation dial 110, the operation of the operation dial 110 becomes valid only in the case where the operation thereof is performed while the top surface is touched. Accordingly, it is possible to effectively prevent the setting from being changed unintentionally.

Further, since the operation becomes valid only by touching the top surface of the operation dial 110, it is possible to ensure good operability.

Furthermore, since the operation dial 110 is electronically locked instead of a mechanical mechanism, it is possible to simplify the configuration of the operation dial 110.

Further, even in the case where the lock is set, since the information is displayed on the sub-display 16 disposed near the operation dial 110, the operation can be performed without being confused. Accordingly, it is possible to ensure good operability.

Furthermore, since a character of “UNLOCK” is displayed on the top surface of the operation dial 110, the operation can be performed intuitively.

In the embodiment, substantially the entire region of the top surface of the operation dial 110 (substantially the entire region on the upper-end surface of the inner peripheral part 112) is set as the contact detection region, but the region where the contact is detected may be limited to a part of the top surface of the operation dial 110. The center portion of the operation dial 110 may be set as the contact detection region. Accordingly, it is possible to effectively prevent the setting from being changed unintentionally. That is, since the operation becomes valid only in the case where the operation is performed while the center portion of the operation dial 110 is touched, it is possible to effectively prevent the erroneous operation. Further, since the region where the contact is detected is the center portion of the operation dial, it is also possible to ensure good operability. That is, other positions cannot be searched by groping, but the position of the rotation center can be found even by groping. Therefore, in a case where the operation is performed in a dark environment, in a case where the operation is performed while a view finder is viewed, or the like, it is possible to ensure especially good operability.

Second Embodiment

In the above-described digital camera 1 of the first embodiment, the operation of the operation dial 110 becomes valid only in the case where the operation dial 110 is operated while the top surface is touched.

In a digital camera 1 of the embodiment, the operation of the operation dial 110 can be switched alternately between valid and invalid every time the top surface of the operation dial 110 is touched. That is, the change in the setting value by the operation dial 110 can be switched alternately between valid and invalid every time the contact is detected by the touch sensor 130.

[Configuration]

A configuration in a second embodiment is basically the same as that of the digital camera 1 of the first embodiment except for a different operation of the switching unit 152.

The switching unit 152 alternately switches between validity and invalidity of the change in the setting value by the operation dial 110 every time the contact with the top surface is detected by the touch sensor 130 which is the contact detection unit.

Therefore, in the digital camera 1 of the embodiment, the touch sensor 130 functions as a so-called toggle type switch.

In the digital camera 1 of the embodiment, the character of “UNLOCK” is not displayed on the top surface of the operation dial 110 (refer to FIGS. 14 and 15).

FIG. 12 is a flowchart showing an operation procedure of the switching unit.

First, it is determined whether the power supply of the digital camera 1 is turned ON (step S21).

In a case where the power supply of the digital camera 1 is turned ON, the change in the setting value by the operation dial 110 is set to be invalid (step S22). That is, in the digital camera 1 of the embodiment, the operation by the operation dial 110 is invalidated at the time the power supply is turned on.

Thereafter, the presence or absence of the contact with the top surface is determined (step S23). That is, it is determined whether the contact with the top surface of the operation dial 110 is detected by the touch sensor 130.

In a case where the contact with the top surface of the operation dial 110 is detected, the switching unit 152 switches between validity and invalidity of the change in the setting value (step S24). That is, in a case where the previous state is valid, the state is switched to invalid. In a case where the previous state is invalid, the state is switched to valid. As described above, since the state is set to be invalid immediately after the power supply is turned on, the state can be switched to valid in a case where the contact is detected for the first time after the power supply is turned on.

In this manner, the switching unit 152 alternately switches between validity and invalidity of the change in the setting value by the operation dial 110 every time the contact with the top surface is detected.

Thereafter, it is determined whether the power supply of the digital camera 1 is turned OFF (step S25). In a case where the power supply is turned OFF, the processing ends.

[Action]

Hereinafter, a setting method by using the operation dial and the sub-display will be described.

FIG. 13 is a flowchart showing a procedure of the setting change by using the operation dial in the digital camera of the embodiment.

First, it is determined whether the operation dial 110 is operated (step S31).

In a case where the operation dial 110 is determined to be operated, then it is determined whether the operation by the operation dial 110 is valid, that is, the change in the setting value by the operation dial 110 is valid (step S32).

In a case where the change in the setting value by the operation dial 110 is valid, the setting value of the item to be set by the operation dial 110 is changed in response to the operation of the operation dial 110 (step S33). For example, in the case where the item to be set by the operation dial 110 is the shutter speed, the shutter speed is changed in response to the operation of the operation dial 110.

On the other hand, in a case where the change in the setting value by the operation dial 110 is invalid, the change in the setting value cannot be performed. In this case, the display of the lock mark m1 on the sub-display 16 is turned on and off (step S34).

In this manner, in the digital camera 1 of the embodiment, the change in the setting value by the operation dial 110 can be switched alternately between valid and invalid every time the top surface of the operation dial 110 is touched. That is, a locked state and an unlocked state (lock release state) of the operation dial 110 can be switched alternately.

FIG. 14 is a plan view showing a display on the sub-display in the case where the change in the setting value is valid.

As shown in FIG. 14, in the case where the change in the setting value is valid, a lock mark is not displayed on the sub-display 16.

FIG. 15 is a plan view showing a display on the sub-display in the case where the change in the setting value is invalid.

As shown in FIG. 15, in the case where the change in the setting value is invalid, the lock mark m1 is displayed on the sub-display 16. In the case where the change in the setting value is invalid, that is, in a case where the operation dial 110 is rotationally operated in the state where the lock is set, the lock mark m1 is turned on and off. Accordingly, it is possible to be more easily recognized that the operation dial 110 is locked.

The system controller 80 executes a predetermined setting program to implement the setting processing.

According to the digital camera 1 of the embodiment as described above, it is possible to lock and unlock the operation dial 110 by touching the top surface of the operation dial 110. Accordingly, it is possible to easily lock and unlock the operation dial 110. Accordingly, it is also possible to effectively prevent the setting from being changed unintentionally.

Third Embodiment

In a digital camera of the embodiment, the item to be set by the operation dial is automatically switched according to the imaging mode.

FIGS. 16 and 17 are respectively a front view and a plan view of the third embodiment of the digital camera to which the invention is applied.

As shown in FIGS. 16 and 17, the digital camera 1 of the embodiment is provided with a mode dial 42 on the top surface of the camera body 10.

The mode dial 42 is a rotary dial for setting the imaging mode. Each symbol of “P”, “S”, “A”, and “M” is displayed on the same circumference at regular intervals on the top surface of the mode dial 42. The symbol “P” represents the program, the symbol “S” represents the shutter speed priority, the symbol “A” represents the aperture stop priority, and the symbol “M” represents the manual. The mode dial 42 is formed such that the click-stop is possible at a position of each symbol with respect to an indicator 42 a. In a case where the symbol “P” is set to the indicator 42 a, the imaging mode is set to the program. In a case where the symbol “S” is set to the indicator 42 a, the imaging mode is set to the shutter speed priority. In a case where the symbol “A” is set to the indicator 42 a, the imaging mode is set to the aperture stop priority. In a case where the symbol “M” is set to the indicator 42 a, the imaging mode is set to the manual.

FIG. 17 shows a case where the shutter speed priority is selected as the imaging mode. In this case, the symbol “S” is set to the indicator 42 a.

As described above, in the digital camera of the embodiment, the item to be set by the operation dial 110 is automatically switched according to the imaging mode.

FIG. 18 is a table representing a relationship between imaging modes and items to be set by the operation dial.

As shown in FIG. 18, in a case where the imaging mode is set to the program, the item to be set by the operation dial 110 is set to the program shift. In this case, in a case where the operation dial 110 is validated and the operation dial 110 is rotated in the plus direction, the shutter speed increases and the F-number decreases. Further, in a case where the operation dial 110 is validated and the operation dial 110 is rotated in the minus direction, the shutter speed decreases and the F-number increases.

Further, in a case where the imaging mode is set to the shutter speed priority, the item to be set by the operation dial 110 is set to the shutter speed. In this case, in a case where the operation dial 110 is validated and the operation dial 110 is rotated in the plus direction, the shutter speed is set to be increased. Further, in a case where the operation dial 110 is validated and the operation dial 110 is rotated in the minus direction, the shutter speed is set to be decreased.

Further, in a case where the imaging mode is set to the aperture stop priority, the item to be set by the operation dial 110 is set to the F-number. In this case, in a case where the operation dial 110 is validated and the operation dial 110 is rotated in the plus direction, the F-number is set to be increased. That is, in the case where the operation dial 110 is validated and the operation dial 110 is rotated in the plus direction, the stop is narrowed. Further, in a case where the operation dial 110 is validated and the operation dial 110 is rotated in the minus direction, the F-number is set to be decreased. That is, in the case where the operation dial 110 is validated and the operation dial 110 is rotated in the minus direction, the stop is opened.

Further, in a case where the imaging mode is set to the manual, the item to be set by the operation dial 110 is set to the shutter speed or the F-number. Whether the shutter speed or the F-number is set depends on the setting by the user. This setting is performed in advance on the setting screen called from the menu. In a case where the user selects the shutter speed, the item to be set by the operation dial is set to the shutter speed. In this case, the setting of the F-number is performed by the rear command dial 41. Further, in a case where the user selects the F-number, the item to be set by the operation dial is set to the F-number. In this case, the setting of the shutter speed is performed by the rear command dial 41.

In a case where the item to be set by the operation dial 110 is the shutter speed, in a case where the operation dial 110 is validated and the operation dial 110 is rotated in the plus direction, the shutter speed is set to be increased. Further, in a case where the operation dial 110 is validated and the operation dial 110 is rotated in the minus direction, the shutter speed is set to be decreased.

In a case where the item to be set by the operation dial 110 is F-number, in a case where the operation dial 110 is validated and the operation dial 110 is rotated in the plus direction, the F-number is set to be increased. That is, in the case where the operation dial 110 is validated and the operation dial 110 is rotated in the plus direction, the stop is narrowed. Further, in a case where the operation dial 110 is validated and the operation dial 110 is rotated in the minus direction, the F-number is set to be decreased. That is, in the case where the operation dial 110 is validated and the operation dial 110 is rotated in the minus direction, the stop is opened.

FIG. 19 is a block diagram showing the schematic configuration of the setting system provided in the digital camera of the embodiment.

The setting system 150 of the embodiment is provided with an imaging mode setting unit 160 instead of the setting item selection unit 156. The imaging mode setting unit 160 sets the imaging mode of the digital camera 1 in response to the operation of the mode dial 42. The imaging mode setting unit 160 is formed of the system controller 80. That is, the system controller 80 executes the predetermined control program to function as the imaging mode setting unit 160.

The setting item setting unit 158 sets the item to be set by the operation dial 110 according to the imaging mode set by the imaging mode setting unit 160.

Further, the display form of the dial-display 132 can be switched between the case where the switching of the setting value by the operation dial 110 is valid and the case where the switching of the setting value by the operation dial 110 is invalid. Accordingly, it is possible to grasp at a glance whether the operation by the operation dial 110 is valid.

The switching of the display form is not limited thereto. In addition, for example, the brightness may be switched between the case where the change in the setting value by the operation dial 110 is valid and the case where the change in the setting value by the operation dial 110 is invalid (for example, the brightness is made bright in the case where the change in the setting value by the operation dial 110 is valid, and the brightness is made dark in the case where the change in the setting value by the operation dial 110 is invalid).

Further, in the case where the operation dial 110 is rotationally operated in the case where the change in the setting value by the operation dial 110 is invalid, the display on the dial-display 132 may be turned on and off. Accordingly, it is possible to be more easily recognized that the operation is invalid.

The method of switching between validity and invalidity of the change in the setting value by the operation dial 110 may be any of methods of the first and second embodiments. In the case of the method of the first embodiment, the operation of the operation dial 110 becomes valid only in the case where the operation dial 110 is operated while the top surface is touched. On the other hand, in the case of the method of the second embodiment, the change in the setting value by the operation dial 110 can be switched alternately between valid and invalid every time the top surface of the operation dial 110 is touched.

Further, the item to be set by the operation dial 110 may be set manually by the user or automatically according to the imaging mode or the like. That is, the item to be set by the operation dial 110 may be set manually on the setting screen or may be switched sequentially in response to the button operation or the like.

The dial-display 132 displays the setting value of the item to be set by the operation dial 110 in the above-described embodiment, and may also display information on the item to be set by the operation dial 110. Further, the dial-display 132 may display only the information on the item to be set by the operation dial 110 or display other pieces of information.

FIG. 37 is a diagram showing an example in a case where the dial-display displays information on an item to be set by the operation dial and a setting value of the item.

As shown in FIG. 37, the dial-display 132 displays information s1 on the item to be set by the operation dial 110 and information s2 on the setting value of the item. FIG. 37 displays the example in the case where the item to be set by the operation dial 110 is the shutter speed. In this case, the character of “SHUTTER SPEED” is displayed as the information indicating that the item to be set by the operation dial 110 is the shutter speed.

In addition, for example, in the case where the item to be set by the operation dial 110 is the F-number, the dial-display 132 displays the character of “IRIS” as the information indicating that the item to be set by the operation dial 110 is the F-number. Further, in the case where the item to be set by the operation dial 110 is the ISO sensitivity, the dial-display 132 displays the character of “ISO” as the information indicating that the item to be set by the operation dial 110 is the ISO sensitivity. Further, in the case where the item to be set by the operation dial 110 is the exposure correction value, the dial-display 132 displays the character of “EXPOSURE CORRECTION” as the information indicating that the item to be set by the operation dial 110 is the exposure correction value. Further, in the case where the item to be set by the operation dial 110 is the imaging mode, the dial-display 132 displays the character of “MODE” as the information indicating that the item to be set by the operation dial 110 is the imaging mode.

Seventh Embodiment

A digital camera of the embodiment also comprises the dial-display on the operation dial and is in common with the digital camera of the sixth embodiment in that the setting value of the item to be set by the operation dial is displayed on the dial-display.

In the digital camera of the embodiment, the displays on the dial-display and the sub-display in the case where the top surface of the operation dial is touched by the finger are different from those of the digital camera of the sixth embodiment.

In the case where the top surface of the operation dial is touched by the finger, the display on the dial-display becomes difficult to view. Thus, in the digital camera of the embodiment, in the case where the top surface of the operation dial is touched by the finger, the sub-display displays the setting value of the item to be set by the operation dial.

«First Display Form»

FIG. 38 is a diagram showing an example of displays on the sub-display and the dial-display in the case where the top surface of the operation dial is not touched by the finger. FIG. 38 shows the example in the case where the item to be set by the operation dial 110 is the shutter speed.

As shown in FIG. 38, in the case where the top surface of the operation dial is not touched by the finger, the dial-display 132 displays the setting value of the item to be set by the operation dial 110. As described above, FIG. 38 shows the example in the case where the item to be set by the operation dial 110 is the shutter speed. In this case, the dial-display 132 displays the setting value of the shutter speed. FIG. 38 shows a case where a currently set shutter speed is 1/60 second. In the dial-display 132, the setting value of the item to be set by the operation dial 110 is displayed in the black character on the white background.

Further, as shown in FIG. 38, in the case where the top surface of the operation dial is not touched by the finger, the sub-display 16 displays the F-number information i2, the ISO sensitivity information i3, the exposure correction value information i4, the imaging mode information i5, the battery remaining amount information i6, and the number of capturable images information i7. The F-number, the ISO sensitivity, the exposure correction value, and the imaging mode are the items that can be set by the operation dial 110.

FIG. 39 is a diagram showing an example of displays on the sub-display and the dial-display in the case where the top surface of the operation dial is touched by the finger.

As shown in FIG. 39, in the case where the top surface of the operation dial 110 is touched by the finger, the display of the setting value disappears and the background color is inverted in the dial-display 132. That is, the whole screen is displayed in black.

On the other hand, the sub-display 16 displays the setting value of the item to be set by the operation dial 110. That is, the sub-display 16 displays the setting value of the shutter speed.

In this manner, in the case where the top surface of the operation dial 110 is touched by the finger, the display on the sub-display 16 can be switched to the display on the dial-display 132. It is possible for the user to confirm the setting value of the item to be set by the operation dial 110 by confirming the display on the sub-display 16. Accordingly, it is possible to ensure good operability.

«Second Display Form»

The displays on the sub-display and the dial-display in the case where the top surface of the operation dial is not touched by the finger are the same as those of the first display form (refer to FIG. 38).

FIG. 40 is a diagram showing another example of displays on the sub-display and the dial-display in the case where the top surface of the operation dial is touched by the finger.

As shown in FIG. 40, in the case where the top surface of the operation dial 110 is touched by the finger, the display of the setting value disappears and the background color is inverted in the dial-display 132.

On the other hand, in the case where the top surface of the operation dial 110 is touched by the finger, a part of the display on the sub-display 16 is switched to the display of the setting value of the item to be set by the operation dial 110. FIG. 40 shows an example in a case where the displays of the battery remaining amount and the number of capturable images are switched to the display of the setting value of the item to be set by the operation dial 110, that is, the display of the shutter speed.

In the example shown in FIG. 40, information id on the setting value of the item to be set by the operation dial 110 is displayed surrounded by a frame line f1. Accordingly, it is possible to easily distinguish the setting value of the item to be set by the operation dial 110.

In this manner, a part of the display on the sub-display 16 may be switched to the display on the dial-display 132. It is possible for the user to confirm the setting value of the item to be set by the operation dial 110 by confirming the display on the sub-display 16. Further, in the case of this example, it is possible to confirm other pieces of information.

«Third Display Form»

The displays on the sub-display and the dial-display in the case where the top surface of the operation dial is not touched by the finger are the same as those of the first display form (refer to FIG. 38).

FIG. 41 is a diagram showing still another example of displays on the sub-display and the dial-display in the case where the top surface of the operation dial is touched by the finger.

As shown in FIG. 41, in the case where the top surface of the operation dial 110 is touched by the finger, the display of the setting value disappears and the background color is inverted in the dial-display 132.

On the other hand, in the case where the top surface of the operation dial 110 is touched by the finger, the original display is reduced and the setting value of the item to be set by the operation dial 110 is displayed in a margin region on the sub-display 16. The original display refers to the display in the case where the top surface of the operation dial 110 is not touched by the finger. In the case where the top surface of the operation dial is not touched by the finger as shown in FIG. 38, the sub-display 16 displays the F-number information i2, the ISO sensitivity information i3, the exposure correction value information i4, the imaging mode information i5, the battery remaining amount information i6, and the number of capturable images information i7. In the case where the top surface of the operation dial 110 is touched by the finger, these pieces of information are reduced as a whole at a predetermined reduction ratio, moved to the front side, and displayed. The setting value of the item to be set by the operation dial 110, that is, the setting value of the shutter speed is displayed in the margin region formed on the back side.

In the example shown in FIG. 41, the information id on the setting value of the item to be set by the operation dial 110 is displayed surrounded by the frame line f1. Accordingly, it is possible to easily distinguish the setting value of the item to be set by the operation dial 110.

In the case of this example, it is also possible for the user to confirm the setting value of the item to be set by the operation dial 110 by confirming the display on the sub-display 16.

According to the digital camera of the embodiment as described above, in the case where the top surface of the operation dial 110 is touched by the finger, the sub-display 16 displays the setting value of the item to be set by the operation dial 110. Accordingly, it is possible to easily confirm the setting value of the item to be set by the operation dial 110 and thus to ensure good operability.

In the case where the top surface of the operation dial 110 is touched by the finger, the display can be switched in the above-described embodiment. However, the display may be switched in a case where the top surface of the operation dial 110 is touched continuously for a certain period of time. For example, in a case where the top surface of the operation dial 110 is touched by the finger continuously for two seconds or more, the display may be switched.

Further, the method of switching between validity and invalidity of the change in the setting value by the operation dial 110 may be any of methods of the first and second embodiments. In the case of the method of the first embodiment, the operation of the operation dial 110 becomes valid only in the case where the operation dial 110 is operated while the top surface is touched. On the other hand, in the case of the method of the second embodiment, the change in the setting value by the operation dial 110 can be switched alternately between valid and invalid every time the top surface of the operation dial 110 is touched. In a case where the switching is performed by the method of the first embodiment, since the display on the top surface is hidden during the operation, the invention is particularly effective.

The switching between validity and invalidity of the change in the setting value by the operation dial 110 is performed by the method of the second embodiment, the display on the dial-display 132 may be switched between the case where the change in the setting value is valid and the case where the change in the setting value is invalid. For example, the color may be inverted between the case where the change in the setting value by the operation dial 110 is valid and the case where the change in the setting value by the operation dial 110 is invalid. Accordingly, it is possible to grasp at a glance whether the operation dial 110 is locked.

Eighth Embodiment

A digital camera of the embodiment also comprises the dial-display on the operation dial and is in common with the digital camera of the sixth embodiment in that the setting value of the item to be set by the operation dial is displayed on the dial-display.

In the digital camera of the embodiment, in the case where the top surface of the operation dial is touched by the finger, the setting value of the item to be set by the operation dial is displayed on the dial-display avoiding a position touched by the finger.

FIG. 42 is a diagram showing yet another example of displays on the sub-display and the dial-display in the case where the top surface of the operation dial is touched by the finger.

The displays on the sub-display and the dial-display in the case where the top surface of the operation dial is not touched by the finger are the same as those of the digital camera of the first display form (refer to FIG. 38).

As shown in FIG. 42, in the case where the top surface of the operation dial 110 is touched by the finger, the information s2 on the setting value of the item to be set by the operation dial 110 is displayed on the dial-display 132 avoiding a position touched by the finger. The display on the sub-display 16 is not changed.

Accordingly, it is possible to prevent the information displayed on the dial-display 132 from not being viewed and thus to ensure good operability.

In the case of this example, it is necessary to detect the region touched by the finger. Therefore, the touch sensor 130 provided with the operation dial 110 is provided with a function of detecting the touched region in addition to the detection of the contact. In particular, the function of detecting the region touched by the finger within the display surface of the dial-display 132 is provided.

The dial-display display control unit 134 displays the information on the setting value of the item to be set by the operation dial 110 on the dial-display 132 avoiding the region where the contact is detected based on the detection result of the touch sensor 130. At this time, the dial-display display control unit 134 adjusts a display size of the information on the setting value of the item to be set by the operation dial 110 and displays the information on the dial-display 132. That is, the display size is adjusted to a size that can be displayed on a region where the contact is not detected, and the information on the setting value of the item to be set by the operation dial 110 is displayed on the dial-display 132.

In a case where the majority on the display surface of the dial-display 132 is touched by the finger, the display of the information is substantially impossible. The information on the setting value of the item to be set by the operation dial 110 may be displayed on the dial-display 132 only in a case where the region where the finger is not touched is equal to or larger than a certain area.

In this manner, according to the digital camera of the embodiment, in the case where the top surface of the operation dial 110 is touched by the finger, the dial-display 132 displays the setting value of the item to be set by the operation dial 110 avoiding the position where the finger is touched. Accordingly, it is possible to easily confirm the setting value of the item to be set by the operation dial 110 and thus to ensure good operability.

In the case where the top surface of the operation dial 110 is touched by the finger, the display can be switched in the above-described embodiment. However, the display may be switched in a case where the top surface of the operation dial 110 is touched continuously for a certain period of time. For example, in a case where the top surface of the operation dial 110 is touched by the finger continuously for two seconds or more, the display may be switched.

Further, the method of switching between validity and invalidity of the change in the setting value by the operation dial 110 may be any of methods of the first and second embodiments. In the case of the method of the first embodiment, the operation of the operation dial 110 becomes valid only in the case where the operation dial 110 is operated while the top surface is touched. On the other hand, in the case of the method of the second embodiment, the change in the setting value by the operation dial 110 can be switched alternately between valid and invalid every time the top surface of the operation dial 110 is touched. In a case where the switching is performed by the method of the first embodiment, since the display on the top surface is hidden during the operation, the invention is particularly effective.

The switching between validity and invalidity of the change in the setting value by the operation dial 110 is performed by the method of the second embodiment, the display on the dial-display 132 may be switched between the case where the change in the setting value is valid and the case where the change in the setting value is invalid. For example, the color may be inverted between the case where the change in the setting value by the operation dial 110 is valid and the case where the change in the setting value by the operation dial 110 is invalid. Accordingly, it is possible to grasp at a glance whether the operation dial 110 is locked.

Further, the information s2 on the setting value of the item to be set by the operation dial 110 is displayed on the region where the contact is not detected while the contact is detected in the above-described embodiment. However, the information s2 on the setting value of the item to be set by the operation dial 110 may be shifted to and displayed at a predetermined position while the contact is detected. In a case where an operation form of a normal operation dial can be specified, it is also possible to assume a position where the display is hidden by the finger due to the operation. Therefore, in such case, the information s2 on the setting value of the item to be set by the operation dial 110 is shifted to and displayed at the predetermined position while the contact is detected. At this time, the display size is reduced and displayed as necessary. Accordingly, it is possible to display the information s2 on the setting value of the item to be set by the operation dial 110 on the dial-display 16 avoiding a substantially touched region. In a case of detecting the contact with the rotation center of the operation dial, the information to be displayed on the dial-display 16 is shifted to and displayed at the predetermined position while the contact is detected as in this example.

Ninth Embodiment

In a digital camera of the embodiment, the item to be set by the operation dial is automatically switched according to the imaging mode. This point is in common with the digital camera of the third embodiment, but a method of switching the imaging mode is different. In the digital camera of the embodiment, the imaging mode can be switched by an operation of swiping the top surface of the operation dial. The swipe operation refers to an operation of moving the finger so as to stroke in a specific direction while the finger touches the top surface.

A basic configuration of the digital camera is the same as the digital camera of the fifth embodiment. That is, the dial-display 132 and the touch sensor 130 that detects the contact with the display surface of the dial-display 132 are provided on the top surface of the operation dial 110. The touch sensor 130 is formed to be capable of detecting the swipe operation in addition to detecting the contact.

FIG. 43 is a diagram showing an example of displays on the sub-display and the dial-display in the digital camera of the embodiment.

As shown in FIG. 43, the dial-display 132 displays information s3 on a currently set imaging mode and the information s2 on the setting value of the item to be set by the operation dial 110.

FIG. 43 shows an example in a case where the currently set imaging mode is the shutter speed priority. In the case where the imaging mode is the shutter speed priority, the item to be set by the operation dial 110 is the shutter speed.

Therefore, in this case, the dial-display 132 displays the information (s3) indicating that the currently set imaging mode is the shutter speed priority and the information (s2) on a currently set shutter speed.

In the case where the currently set imaging mode is the shutter speed priority, a symbol of “S” is displayed as the information s3 on the currently set imaging mode as shown in FIG. 43. FIG. 43 shows an example in a case where the currently set shutter speed is 1/60 second. In this case, “ 1/60” is displayed as the information s2 on the setting value of the item to be set by the operation dial 110.

The sub-display 16 displays pieces of information other than the item to be set by the operation dial 110. The pieces of information displayed on the sub-display 16 include at least pieces of information on the setting values of the items that can be set by the operation dial 110.

In the currently set imaging mode is the shutter speed priority, the sub-display 16 displays pieces of information other than the shutter speed and the imaging mode, that is, respective pieces of information i2 to i4 of the F-number, the ISO sensitivity, and the exposure correction value as shown in FIG. 43. In addition, in the digital camera of the embodiment, the sub-display 16 displays the battery remaining amount information i6 and the number of capturable images information i7.

FIG. 44 is a diagram describing the method of switching the imaging mode by the swipe operation on the top surface of the operation dial.

In the digital camera of the embodiment, the imaging mode can be switched by swiping the top surface of the operation dial 110 in the lateral direction.

The imaging mode setting unit switches the imaging mode based on the output from the touch sensor 130.

Here, in a case where the top surface of the operation dial 110 is swiped in the right direction, the imaging mode can be switched in order of the program, the shutter speed priority, the aperture stop priority, and the manual. Further, in a case where the top surface of the operation dial 110 is swiped in the left direction, the imaging mode can be switched in a reverse order. That is, the imaging mode can be switched in order of the manual, the aperture stop priority, the shutter speed priority, and the program. For example, in the case where the currently selected imaging mode is the shutter speed priority, in the case where the top surface of the operation dial 110 is swiped in the right direction, the imaging mode can be switched to the aperture stop priority.

FIG. 44 shows a display on the dial-display 132 during the switching of the imaging mode. Specifically, the display on the dial-display 132 during the switching from the shutter speed priority to the aperture stop priority is shown. As shown in FIG. 44, the display on the dial-display 132 is switched by a scroll.

FIG. 45 is a conceptual diagram of the scroll of the display on the dial-display.

As shown in FIG. 45, the swipe operation is performed on the top surface of the operation dial 110 in the lateral direction to move contents of a display screen on the dial-display 132 in the lateral direction, and thus the display is switched. The contents of the screen move in the direction of swiping.

(A), (B), (C), and (D) of FIG. 46 are diagrams showing examples of the display on the dial-display in each imaging mode.

(A) of FIG. 46 shows a display screen of the dial-display 132 in a case where the imaging mode is the program.

In a case where the imaging mode is set to the program, the item to be set by the operation dial 110 is set to the program shift. In this case, the dial-display 132 displays information indicating that the currently set imaging mode is the program and pieces of information on the currently set shutter speed and F-number. In the example shown in (A) of FIG. 46, a symbol of “P” is displayed as the information indicating that the currently set imaging mode is the program. Further, (A) of FIG. 46 shows an example in a case where the currently set shutter speed is 1/60 second and the F-number is F5.6.

(B) of FIG. 46 shows a display screen of the dial-display 132 in a case where the imaging mode is the shutter speed priority.

In a case where the imaging mode is set to the shutter speed priority, the item to be set by the operation dial 110 is set to the shutter speed. In this case, the dial-display 132 displays information indicating that the currently set imaging mode is the shutter speed priority and information on the currently set shutter speed. In the example shown in (B) of FIG. 46, a symbol of “S” is displayed as the information indicating that the currently set imaging mode is the shutter speed priority. Further, (B) of FIG. 46 shows an example in a case where the currently set shutter speed is 1/60 second.

(C) of FIG. 46 shows a display screen of the dial-display 132 in a case where the imaging mode is the aperture stop priority.

In a case where the imaging mode is set to the aperture stop priority, the item to be set by the operation dial 110 is set to the F-number. In this case, the dial-display 132 displays information indicating that the currently set imaging mode is the aperture stop priority and information on the currently set F-number. In the example shown in (C) of FIG. 46, a symbol of “A” is displayed as the information indicating that the currently set imaging mode is the aperture stop priority. Further, FIG. (C) of 46 shows an example in a case where the currently set F-number is F5.6.

(D) of FIG. 46 shows a display screen of the dial-display 132 in a case where the imaging mode is the manual.

In a case where the imaging mode is set to the manual, the item to be set by the operation dial 110 is set to the shutter speed or the F-number. Whether the shutter speed or the F-number is set depends on the setting by the user. In a case where the user selects the shutter speed, the item to be set by the operation dial is set to the shutter speed. In this case, the setting of the F-number is performed by the rear command dial 41. Further, in a case where the user selects the F-number, the item to be set by the operation dial is set to the F-number. In this case, the setting of the shutter speed is performed by the rear command dial 41.

In the case where the item to be set by the operation dial 110 is the shutter speed, the dial-display 132 displays information indicating that the currently set imaging mode is the manual and information on the currently set shutter speed. On the other hand, in the case where the item to be set by the operation dial 110 is the F-number, the dial-display 132 displays information indicating that the currently set imaging mode is the manual and information on the currently set F-number. The example shown in (D) of FIG. 46 shows an example in the case where the item to be set by the operation dial 110 is the shutter speed. Further, in the example shown in (D) of FIG. 46, a symbol of “M” is displayed as the information indicating that the currently set imaging mode is the manual. Further, (D) of FIG. 46 shows an example in a case where the currently set shutter speed is 1/60 second.

The imaging mode can be switched in order of the program, the shutter speed priority, the aperture stop priority, and the manual by swiping the top surface of the operation dial 110 in the right direction.

As described above, the imaging mode setting unit switches the imaging mode based on the output from the touch sensor 130. The setting item setting unit 158 sets the item to be set by the operation dial 110 according to the imaging mode set by the imaging mode setting unit.

The sub-display display control unit 72A controls the display on the sub-display 16 according to the set imaging mode. Similarly, the dial-display display control unit 134 controls the display on the dial-display 132 according to the set imaging mode.

According to the digital camera of the embodiment as described above, it is possible to switch the imaging mode by the operation of swiping the top surface of the operation dial 110. Accordingly, it is possible to easily switch the operation mode. Further, since the dial-display 132 displays the information on the set imaging mode, it is also possible to easily switch the operation mode visually. Furthermore, since the dial-display 132 displays also the information on the setting value of the item to be set by the operation dial 110, it is possible to realize good operability.

The imaging mode is switched by the operation of swiping the top surface of the operation dial in the above-described embodiment. However, the operation mode may be switched by a flick operation. The flick refers to an operation of touching the top surface with the finger and then moving the finger so as to flip.

Further, the method of switching between validity and invalidity of the change in the setting value by the operation dial 110 may be any of methods of the first and second embodiments. In the case of the method of the first embodiment, the operation of the operation dial 110 becomes valid only in the case where the operation dial 110 is operated while the top surface is touched. On the other hand, in the case of the method of the second embodiment, the change in the setting value by the operation dial 110 can be switched alternately between valid and invalid every time the top surface of the operation dial 110 is touched. In a case where the switching is performed by the method of the first embodiment, since the display on the top surface is hidden during the operation, the invention is particularly effective.

Further, the switching between validity and invalidity of the change in the setting value by the operation dial 110 is performed by the method of the second embodiment, the display on the dial-display 132 may be switched between the case where the change in the setting value is valid and the case where the change in the setting value is invalid. For example, the color may be inverted between the case where the change in the setting value by the operation dial 110 is valid and the case where the change in the setting value by the operation dial 110 is invalid. Accordingly, it is possible to grasp at a glance whether the operation dial 110 is locked.

In a case where the finger touches the display surface of the dial-display 132, the display may become difficult to view by the finger. Therefore, for example, in a case where the finger touches the same position continuously for a certain period of time or more, the display may be performed avoiding the position touched by the finger.

FIG. 47 is a diagram showing an example of a display on the dial-display in the case where the finger touches the same position continuously for a certain period of time or more.

As shown in FIG. 47, in the case where the finger touches the same position continuously for a certain period of time or more, the information to be displayed on the dial-display 132 is displayed avoiding the position touched by the finger. In this case, the touch sensor is provided with a function of detecting the region touched by the finger.

Other Embodiments

[Item to be Set by Operation Dial]

In each embodiment described above, the shutter speed, the F-number, the ISO sensitivity, the exposure correction value, and the imaging mode are set by the operation dial. However, the item to be set by the operation dial is not limited to the above items. It is possible to set the item as appropriate depending on the function provided with the digital camera.

The contact detection unit is formed of the touch sensor in the above-described embodiment, but the configuration of the contact detection unit is not limited thereto.

Further, in a case of detecting only the contact, the contact detection region may be limited to a part thereof. For example, the contact detection region may be limited to a center portion of the top surface of the operation dial.

[Modification Example of Detection of Contact]

A so-called dead zone may be provided for the detection of the contact. That is, it is preferable not to detect instantaneous finger contact. Similarly, it is preferable not to detect also a case where the finger is instantaneously released.

In order to provide the dead zone, for example, the contact is detected at regular time interval. In this case, it is determined whether the contact is continuously detected to determine the presence or absence of the contact. In a case where the contact is continuously detected, the contact is determined to be present. In the case of the instantaneous contact, since the contact is not continuously detected, the contact is not determined to be present. Further, even in the case where the finger is instantaneously released, it can be recognized that the contact is continued as long as the finger is touched before the next detection.

In this manner, the operation can be performed more stably by determining also duration of the contact and responding with hysteresis.

[Other Examples of Display Form in Case Where Change in Setting Value by Operation Dial is Valid and in Case Where Change in Setting Value by Operation Dial is Invalid]

In the case where the change in the setting value by the operation dial is invalid, the lock mark is displayed on the sub-display in the above-described embodiment. However, a method of notifying by the sub-display that the change in the setting value by the operation dial is invalid is not limited thereto. For example, it may be notified that the change in the setting value by the operation dial is invalid by changing the background color of the sub-display.

[Other Examples of Method of Notifying that Change in Setting Value by Operation Dial is Invalid]

(1) Notification by Sound

In a case where the digital camera is provided with a sound output unit such as a speaker, the user may be notified that the change in the setting value by the operation dial is invalid by using the sound output unit. For example, in the case where the operation dial is rotationally operated in the case where the change in the setting value by the operation dial is invalid, a sound such as a notification sound or a warning sound is output from the sound output unit. In this case, the digital camera is provided with a sound output control unit. In the case where it is detected that the operation dial is rotationally operated in the state where the change in the setting value by the operation dial is invalid, the sound output control unit outputs the sound such as the notification sound or the warning sound from the sound output unit.

Further, in the case where the digital camera is provided with the sound output unit such as the speaker, a pseudo-rotation operation sound may be output in conjunction with the rotation operation of the operation dial. In this case, the rotation operation sound may be switched between the case where the change in the setting value by the operation dial is valid and the case where the change in the setting value by the operation dial is invalid. Alternatively, the rotation operation sound may be output only in the case where the change in the setting value by the operation dial is valid.

(2) Notification on Main-Display

In a case where the camera body is provided with the main-display as the digital camera of the above-described embodiment, the main-display may display a state of the operation dial. That is, the main-display may display whether the change in the setting value by the operation dial is valid. In a case where the camera body is provided with the electronic view finder, the same display may be performed also on the electronic view finder.

[Other Forms of Dial-Display Section]

The shape of the dial-display as one example of the dial display section is circular in the above-described embodiment, but the shape of the dial display section is not limited thereto. For example, the shape thereof may be rectangular or polygonal.

FIG. 48 is a plan view of the sub-display and the operation dial having a rectangular dial display section.

In the operation dial 110 shown in FIG. 48, the dial-display 132 that is an example of the dial display section has a rectangular display surface.

In this manner, the shape of the dial display section does not necessarily match the shape of the top surface of the operation dial (shape of the upper-end surface of the inner peripheral part 112), and various shapes may be employed.

[Other Examples of Dial-Display Section]

The dial-display forming the dial display section is formed of the LCD in the above-described embodiment, but the dial-display forming the dial display section is not limited thereto. In addition, the dial-display may be formed of a self-luminous display or the like such as electronic paper, a memory liquid crystal display, or an organic electroluminescent display (EL).

The electronic paper is a thin display that has thinness and visibility at the same level as those of paper, and means a display of which contents to be displayed can be rewritten. The memory liquid crystal display is a liquid crystal display that has a function to be capable of maintaining contents displayed on a screen even though a power supply is turned off. Both of the electronic paper and the memory liquid crystal display can ensure good visibility even in an environment where surroundings are bright. Further, a display on the dial display section can be confirmed even in a case where the power supply of the camera is turned off.

Further, in a case where the dial-display is formed of the LCD, it is possible to ensure good visibility even in an environment where surroundings are bright by employing a reflective LCD as the display. In the case where the dial-display is formed of the reflective LCD, it is preferable to comprise illumination.

Similarly, the sub-display which is the display section may also be formed of the self-luminous display or the like such as the electronic paper, the memory liquid crystal display, or the organic EL display.

[Other Examples of Disposition of Display Section with Respect to Operation Dial]

The sub-display 16 is disposed at the position on the left oblique front side of the operation dial 110 on the top surface of the camera body 10 in the above-described embodiment. However, the disposition position of the sub-display 16 with respect to the operation dial 110 is not limited thereto.

However, since the operability and the visibility deteriorate in a case where the sub-display 16 is disposed at a position away from the operation dial 110, it is preferable to dispose the sub-display 16 near the operation dial 110.

Here, the “near” refers to a distance relationship to the extent that the sub-display 16 and the operation dial 110 are disposed adjacent to each other as shown in FIG. 3.

It is possible to enhance the relationship between the sub-display 16 and the operation dial 110 by disposing the sub-display 16 near the operation dial 110 and thus to provide better operability. That is, since the setting can be confirmed right near the operation dial 110 by disposing the sub-display 16 near the operation dial 110, in a case where the operation is performed while the operation dial or the dial-display is viewed, it is possible to reduce movement of line of sight and thus to provide good operability without stress. Further, it is also possible to realize an intuitive operation.

Further, in the case where the sub-display 16 is disposed near the operation dial 110, it is preferable to dispose the sub-display 16 on the left side than on the right side of the operation dial 110 and on the upper side than on the lower side of the operation dial 110 from the viewpoint of operability since the sub-display 16 is hardly hidden by the hand operating the operation dial 110.

FIG. 49 is a plan view showing another example of a layout of the operation dial and the sub-display.

In the example shown in FIG. 49, the sub-display 16 is disposed at a position on the left side of the operation dial 110 on the top surface of the camera body 10. Accordingly, it is possible to prevent the display on the sub-display 16 from being hidden by the finger of the hand operating the operation dial 110.

FIG. 50 is a plan view showing still another example of the layout of the operation dial and the sub-display.

In the example shown in FIG. 50, the sub-display 16 is disposed at a position on the front side of the operation dial 110 on the top surface of the camera body 10. In the example shown in FIG. 50, a plurality of dials D1 and D2 are provided on the top surface of the camera body 10. Further, in the example shown in FIG. 50, the outer diameter of the operation dial 110 and the screen size of the sub-display are reduced. In this manner, it is possible to set the outer diameter of the operation dial and the screen size of the sub-display as appropriate depending on the size of the camera body or the like.
